Benefits of technology

[0022] Another object of the present invention is to provide a front panel operating apparatus of a car display device that enables a stable manipulation of the front panel for opening and closing the display part.

Problems solved by technology

Further, when the front panel 30 rotates downwardly, there occurs a problem in watching the display section 32 formed in front of the front panel 30 and operating the operating buttons 33.
However, a smooth movement of the front panel is hindered sometimes because the front panel is sensitive to external conditions such as temperature, humidity and so on owing to a complicated mechanical operation.
Also, the front panel has another disadvantage because a sufficient device reliability cannot be obtained due to the complicated mechanical operation when inserting or withdrawing compact disc, mini disc, cassette tape and so on.

embodiment 1

[0063] A first preferred embodiment of a front panel operating apparatus of a car display device according to the present invention will now be described. As shown in FIGS. 6-12, a front panel operating apparatus of the car display device such as a car audio according to a first embodiment of the present invention can include a main chassis 100 preferably having a cylindrical shape of which one end is opened for accommodating a compact disc player 102 and a cassette player 103 or the like, and a front panel 125 provided at the front side of the main chassis 100 that can move in upward and downward directions to adjust its inclination angle. Preferably, the inclination angle can be set to a user desired angle between an open and closed position or with fine increments or graduations between the open and closed positions. A supporting panel 120 can be positioned inside a lower side of the main chassis 100 to be withdrawn in forward and backward directions, and a protruded section 137 ...

embodiment 2

[0084] A second embodiment of a vehicle display device according to the present invention will now be described with reference to FIGS. 13-16. The second embodiment according to the present invention is similar to the first embodiment, but has at least a difference from the first embodiment in the supporting panel driving section. Descriptions of the second embodiment will concentrate on the supporting panel driving section.

[0085] In the first embodiment, the torque of the driving motor 133 can be transferred to the rack 131 via the single pinion 134 can have a disadvantage in the reliable power transmission. The second embodiment can constitute a supporting panel driving section capable of increasing or guaranteeing a reliability of such power transmission.

[0086] As shown in FIGS. 13 and 14, a supporting panel driving section according to the second embodiment of the present invention can include a driving motor 230 preferably coupled to a main chassis (not shown in the drawings)...

embodiment 3

[0094] A third embodiment of a vehicle display device according to the present invention will now be described. The third embodiment according to the present invention is similar to the second embodiment, but has at least a difference from the second embodiment in the shape, structure and operations of a pinion.

[0095] As described above, the second embodiment can include the pinion 245 with the large gear section 247 in mesh with a final gear of the gear train 240, and the small gear section 246 in mesh with the rack 212 on the supporting panel 210. In this configuration, the supporting panel 210 on which the rack 212 is installed can be spaced by a predetermined margin from the main chassis preferably to enhance the assembly convenience and provide smooth operation.

[0096] Accordingly, a force is applied to the engagement between the pinion 245 and the rack 212 can depend on movement of the supporting panel 210 so that a central distance between the pinion 245 and the rack 212 can...

Abstract

A front panel operating apparatus and method of a vehicle display device such as a car audio can include a main chassis for accommodating an audio device, a front panel provided in the front side of the main chassis that opens or closes to allow access to a record medium for the audio device. The front panel can have a display part in the front side thereof. A supporting panel can be hinge-coupled to a lower side of the front panel to move a lower end of the front panel forward and backward by sliding from a prescribed location of the main chassis in forward and backward directions of the main chassis. A vertical guide can be formed at the front side of the main chassis, and a protrusion formed on the front panel can be inserted into the vertical guide for controllably moving an upper portion of the front panel up and down.
